I built a full size beacon pyramid. It shows that I selected beacon power and it shows the haste symbol in upper right corner.
What I expected to happen was...:
To be able to instant mine stone.
What actually happened was...:
I mine at the same speed with or without the beacon being activated.
Steps to Reproduce:
Built a full size beacon on my world seed: -7573681997578590922. Beacon is placed exactly at -134, 21, -118. with iron blocks.
Gave the beacon several iron ingots and clicked haste and green check mark.
I have closed captions on, where I can read the sounds around me. So it shows beacon power activate or similar. Not sure exactly.
Go and mine directly beside, under, above it and mine at normal rate.
I am using netherite picks, two of them, both efficiency 5, unbreaking 3, mending, and one has silk touch and the other has fortune 3.
Apparently I wasn't doing something right. I have it now. Sorry for the inconvenience.
